ANTISKD CHAIN AND ATTACHENG MEANS THEEEFRP application inea Marca 1i, 1922. serial no. erases..

To all' whom t may concern;

Be it known that l, iiucusrr P. Seurin,

a citizenv ot the United States, and a resi? dent oit the city of Chicago, in the county ot' Cool; and State oit illinois, have invented certain new and usei'ul Improvements in Antislzid Chains and Attaching Means Theretor; and l do herehy declare that the following a full, clear, and exact description ot' the. saine, reference being had tov the.

accompanying drawings, andtolthe nuirer-y als o reference rnarlred thereon, which torni i lt is also an ohject oit this intention, toA provide anchoring lugs that take up the.

slack ot the chains.

With these and other objects in View which will become Inoreapparent in the 'following description and disclosures in the drawing, this invention comprises the novel mechanism and combinations hereinafter described and more particularly pointed out and defdned in the appended claims.

Figure 11 is an enlarged fragmentary View of another inodied 'form ot this in- As shown on the drawings:

ln referring to the drawings, especiallyk to Figures l to l, it will beiohserved that a plurality. ot independent anti-skid chains l have. been illustrated, and that these chains extend transversely ofthe wheel and are j secured at, their ends to ineans attached on opposite sides ot the 'bolts 2 of the wheel which usually lugs.

The anchoring ineans for each chain on earlier sustain the deinountable rini one side of the wheel comprises a speciallf constructed demountable rinjL anchor plate or lug i which has a pair of spaced hooks or prongs at its upper end and a pair ot` ears just below the hooks for supporting a latch t3 which4 has laterally projecting pintles 7 journalled in bearing apertures in4 said ears v5, said latch being designed to lit; bvetween the hoolrs Lll and cooperate therewithl` :for securely latching said chain on the wheel. rllhe latch v6l is iinpelled; upwardly by a spring 8, provided with a pair of spaced coils surrounding thev pintles ofv the latch adjacent the. ears, 5, the ends of said spring. bearing against the. anchory lug ,3 and thev bridging portion 9 between thecoils bearing rllhe anchoring lug 3,. is provided with the usual wedging lug: l0

' for retaining the clincher rim 1 1 in position and the tulcrunji lug l2 at .the lower.' end thereof; The clips 3, kare provided withv apertures to, receivev the halts 2 andare clamped against the, wheel by the nuts 13.

rtheanchoring means lel on the opposite side of the wheel are similar to the anchor lugs 3 with the exception that they do not have the wedging lugs l0 tor retaining the tire, norv the. i''ulcrun'i lugs l2, for reasons which appear obvious.

The ends of each ot the chains l are connected to linlrs or hails lwliich are in the form of loops converging from their upper ends to substantially a closed point, the lower ends being bent outwardly at substantially right angles to a central longitudinal axis of the links to provide trunnion members 16 adapted to tit under the hook members d for l'irmly securing the chains to the wheel.

lt is evident that with the anchoring means 3 and 14 attached to the wheel, the separate chains may be successively anchored to the wheel in a very few moments. To anchor a chain to the wheel at` 4any predetermined point, it is only necessary to move the latcht on one side ot the wheel downwardly atA that point, position the trunnions 16 under the hooks e, then allowing the latch 6 to Aspring upwardly against the bail 15 tor lsecurely interlocking the same, then bringing the other end of the chain to the opposite side of the wheel, and anchoring the trunnion 16 under the hooks Ll, as already explained.

1n the modified form ot this invention, as disclosed in Figures 5 to 6, the anchoring means for the chains consists of opposite lugs 17 and 18 secured in position on the sides of the rim by means oit the bolt 2. r1`hese lugs are provided with lower flanges 19 which embrace the :telloe oi the wheel. rllhe lugs 17 and 18 have laterally projecting spaced ears 2O in which icl-shaped or arcuate grooves 21 open at their inner ends to provide entrance slots are formed for receiving the trunnions 16 on the bail menibers 15 to which the chains 1 are attached. vLatch members 6a are yieldiigly supported on small rod shafts 7 similar to the vay in which the latch members 6 are supported,

and are spring-pressed against the bails 15' to hold the same effectively in the grooves 21.

ln using these modified iforms ot anchoring lugs 17 and 18, the'trunnions 16 are adapted to normally engage the upper walls 21a of the grooves 20. However when the load of the vehicle passes over or rests upon a chain 1 and compresses the tire at that point, a slack will be produced, in the cha in, and this slack will be taken up by a movement of the trunnions 16' around the curved grooves 21.

instead oi making the grooves 21 oi curved formation tor the purpose ot takin up the aforementioned slack, the grooves might be made straight and suitably inclined as is illustrated by the grooves 2 in the anchoring lug 23 shown in Figures 9 and 10, whereby the slack of the chans will be more quickly taken up, and entrance slots 9A- may be formed in the walls oi' these straight inclined grooves for admitting the trunnions 16 of the hails 15, as is obvious. The entrance slots 24 are not coerztensive with the horzontal width oi' the grooves wlfierebj,vv shrouds 24a (Fig. 9) are formed which prevent the trunnions on the bail member l5 from being withdrawn withoutl pressing the same together. lt desirable, spring latches such as illustrated may be used to close the notches 211.

The manner ot attaching the chains to thesemodified forms ot lugs is fairly obvious; a bail member 15 oi a chain being i'irst anchored upon one side oi' the wheel, and the chain passed overthe tire and the other bail member secured to the opposite lug.

rlhe anchoring lug 23 may be made with a plurality of spaced setsot grooves for anchoring a plurality of chains, las shown in Figure 11, in which the modied form of anchoring lug 232L extends between two spokes, being secured to the elloe of the wheelby a bolt 25 intermediate the spokes. ln the present instance, the anchoring lug 23a is provided with two sets of grooves 22 and two entrance slots '211, whereby two chains may be anchored to the anchoring lug 28a.

lit is characteristic of this invention that a plurality of independent chains are used and that each is separatelyl anchored to the wheel by novel orms oit lugs that allow rapid assembling, and that the chains are removably latched to the lugs. 1t is further characteristic oit this invention that the lugs may be constructed to take up the slack in the chains.

l am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and l therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
